VERY RARE Star Trek Green Stone Starfleet Academy Gold Tone Ring! This ring is used but in good condition. There is wear on the ring as seen in photos. This ring is a great addition to that Star Trek collection. The ring itself is made from a gold tone material I’m not sure of what. Inside the ring is marked TM Paramount pictures. This is a very rare ring in great shape but used. I have the ring on a ring sizer to show the size of the ring. Please look at photos. Any questions please ask.
